I can help with one thing. Pencils. Although more expensive, I find that Mechanical Pencils are much less texturally and audibly annoying. It is possible to get a comfort grip for a Mechanical Pencil so calluses are less of a problem.

Once I got my first Mechanical Pencil for Drafting class, I never went back to regular pencils again.

On reading, is the problem visual or textural? If the problem is visual, consider getting an Irlen Overlay or Irlen Lenses. If the problem is textural, consider E-books (or books you can read electronically).

Have you ever used gloves when writting or touching papers, I know it looks funny and much harder to write while wearing gloves but I found sometimes it is less painful and upsetting.
